Iron at -40" in acidic solutions of liquid ammonia displays an active region and a passive region. The dissolution reaction is pIGindependent and irreversible, the first charge transfer step being ratsdetermining. Passivation occurs through the adsorption of solvent oxidation products, initially pro
km dissolution as well as hydrogen evolution was studied in HCI and HBr acetonitrile solutions in a concentration range between 2.8 x IO-' M and 9.8 x 10m4 M. Halide concentration was changed by adding lithium halide to some of the previous solutions. Measurements were performed at 00Β°C. Current ef
